Answer:

Step-by-step explanation:

$2x+\frac{12}{7}=3x+\frac{5}{4}\\\\2x-3x=\frac{5}{4}-\frac{12}{7}\\\\-x=\frac{5*7}{4*7}-\frac{12*4}{7*4}\\\\-x=\frac{35}{28}-\frac{48}{28}\\\\-x=\frac{35-48}{28}\\\\-x=\frac{-13}{28}\\\\ x=\frac{13}{28}$

What is the equation of the following line? be sure to scroll down first to see all answer options

andreyandreev [35.5K]

Answer:

The equation for the following graph:

$y = -\frac{1}{5}x$

Step-by-step explanation:

- You first need to find the slope by using the <u>slope formula</u>:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

(where $(x_{1},y_{1})$ is the first point and $(x_{2}, y_{2})$ is the second point)

-Use the given points $(0,0)$ and $(10, -2)$ from the graph for the formula:

$m = \frac{-2 - 0}{10 - 0}$

Then, you solve:

$m = \frac{-2 - 0}{10 - 0}$

$m = -\frac{1}{5}$

After you have found the slope, use the slope $-\frac{1}{5}$ and the first point $(0,0)$ for the <u>point-slope formula:</u>

$y - y_{1} = m ( x - x_{1})$

<u>(</u>where $m$ is the slope and $(x_{1}, y_{1})$ is the first point)

$y - 0 = -\frac{1}{5} ( x - 0)$

Then, you solve:

$y - 0 = -\frac{1}{5} ( x - 0)$

$y - 0 = -\frac{1}{5}x - 0$

$y - 0 + 0 = -\frac{1}{5} - 0 + 0$

$y = -\frac{1}{5}x$

So, the equation for the following graph is $y = -\frac{1}{5}x$ .

Can someone help me with this?? If you can't see the picture don't bother to answer.

J is correct. the scale is balanced, so x = 1. there are 9 1’s on the right, and 6 1’s on the left. there are 3 more blocks, and they would have to each be 1.
